Halfway Between 29 and 815

When you ask "What number is halfway between 29 and 815?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=29 and Y=815.

Halfway Between Line

To find the number halfway between 29 and 815, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 29 and 815 into our formula, we get:

(29 + 815)/2 = 422

Thus, the number halfway between 29 and 815 is 422.

To check that our answer is correct, we subtract 29 from 422 and subtract 422 from 815 and compare the two numbers:

422 - 29 = 393
815 - 422 = 393

As you can see, the halfway number is 393 higher than 29 and 393 lower than 815. Therefore, our halfway between answer of 422 above is correct.
